k, now the question is what in the world would cause it to do that? You are right, pretty interesting

I don't think this shell has been fired,there are NO signs of being struck by a firing pin,which would be on the bottom edge (rimfire).Possibly over exposure from heat ?

I can't believe I didn't notice that...not a dimple one that I can see.

Weird... that is odd.

Probably was in a confined container and heat set it off and melted the lead. Monty

Throw non jacketed bullets in a really hot fire. The Lead melts often before the powder inside blows the bullet off the casing(no pressure buildup_

 

[CRUSADER]

agree with everyone, its been in a fire.

looks to be too much material to have come from the lead bullet portion and seems to be the wrong colour for lead,looks like iron staining in the second pic.just my 2 cents.
